I have a quadrotor aircraft (4 motors/propellers around a center housing) with some electronics in an electronics housing. Looking to cool the electronics with propeller downwash.
I have a vent on the side of the electronics housing and one on the bottom. I assume the pressure on bottom P0 is atmospheric. Trying to determine which way the air will flow.
Would pressure P1 be higher or lower than atmospheric?
The propellers do work on the fluid and increase the dynamic pressure but there is also air at high velocities flowing past the side vents. Having trouble consolidating propeller dynamics with Bernoulli's principle.
